آلیاژ تیتانیوم ti-6al-4v یکی از پرکاربردترین آلیاژهای صنعتی است که بیشترین استفاده را در صنایع مهم و پر مخاطره دارد، یکی از ملزومات ماشینکاری چنین قطعاتی دستیابی به سلامت سطح مناسب است. ماشینکاری تخلیه الکتریکی با استفاده از ذرات معلق در دی الکتریک، فرآیندی است که مکانیسم آن با فرآیند ماشینکاری تخلیه الکتریکی سنتی متفاوت است و اغلب به منظور دستیابی به صافی سطح مناسب در ماشینکاری تخلیه الکتریکی ...

The esophageal Doppler monitor (EDM) is a clinically useful device for minimally invasive assessment of cardiac output, preload, afterload, and contractility. An empirical model, based upon the logistic function, has been developed. Use of this model illustrates how the EDM could estimate the net effect of aortic and non-aortic contributions to inertia, resistance, and elastance within real tim...

EDM is an unconventional electro thermal machining process used for manufacturing geometrically complex or hard material parts that are extremely difficult-to-machine by conventional machining process. The process involves a controlled erosion of electrically conductive materials by the initiation of rapid and repetitive spark discharges between the tool and work piece separated by a small gap ...

Contemporary challenges for enterprise document management (EDM) include managing a mixture of technologies, recognizing the needs of several user roles and groups, and pursuing effective processes utilizing documents in digital form. Responding to these challenges means gathering and scrutinizing organizational metadata describing the organization's information resources. Despite the volume of...

Italian ryegrass (Lolium multiflorum Lam.) is one of the most important forage grass species in Europe. In Portugal 34% of the cultivated area is dedicated to animal fodder. Italian ryegrass area in Entre Douro e Minho (EDM) region was mainly with landraces. Changes in traditional agricultural systems are contributing to a major loss of genetic diversity mainly to landraces. Portuguese Italian ...

Abstract An n × n matrix D is a Euclidean distance matrix (EDM) if there exist p, . . . , pn in some Euclidean space such that dij = ||pi − pj ||2 for all i, j = 1, . . . , n. Let D be an EDM and let Eij be the n×n symmetric matrix with 1’s in the ijth and jith entries and 0’s elsewhere. We say that [lij , uij ] is the yielding interval of entry dij if it holds that D+ tE ij is an EDM if and on...

Electro discharge machining (EDM) is a process that uses an electric sparks to generate the high temperature and melt the workpiece. One of the EDM process is drilling. In EDM drilling, an electro thermal mechanism is introduced between the electrode and work piece to create the hole. The hole size is dependent on the diameters of electrode used during the drilling process. The present study pe...

In 2013/14 the Deutsche Digitale Bibliothek (DDB) changed its data model from the CIDOC conceptual reference model to the Europeana Data Model (EDM). This decision was taken against the background of two major mandates the DDB has to fulfill: as a portal and as a platform the DDB is providing access to digital objects from German cultural heritage and research institutions. The DDB also aims to...

به منظور بررسی ساختار و رفتار هیدرولیکی جریان در رودخانه­ها و کانال­های مرکب، دبی و شیب خط انرژی اهمیت بالایی دارند. با تقسیم مقطع عرضی این کانال­ها به زیر ناحیه­های آن یعنی کانال اصلی و بسترهای سیلابی، دبی جریان به صورت جداگانه در هر زیر ناحیه قابل تعیین است و آنگاه دبی کل مقطع از مجموع آنها بدست می­آید. این روش به روش کانال تقسیم شده (dcm) معروف است. روش دیگری نیز به روش کانال ساده (scm) موسو...

Complete two-loop electroweak corrections to leptonic anomalous magnetic moments have been calculated recently using asymptotic expansions of Feynman diagrams. Techniques developed in that context can also be applied to the electric dipole moments (EDM) of fermions. In the Standard Model the EDM was proved to vanish at two loops. In this talk we discuss a simplification of that proof.
